CONCOA 332 Series Regulator
The CONCOA 332 Series is a five-port, stainless steel, dual-stage cylinder regulator designed for primary pressure control of high-purity inert gases (up to grade 5.5), including mildly reactive gases—but not toxic or highly corrosive gases. Its two-stage design minimizes pressure fluctuations from cylinder depletion, providing stable delivery pressure for critical applications. Factory-configurable options make it ideal for university labs, research facilities, and pharmaceutical manufacturing.

Reliance RWC 5 Litre Heating Expansion Vessel Tank with Replaceable Membrane Pre Set 1 Bar - XVES100020
The Reliance Valves Aquasystem Stainless Steel Expansion Vessel is specifically designed for heating applications. Available in capacities ranging from 2 litres to 5000 litres, these vessels operate under maximum pressure ratings of 8.0 to 10.0 bars. Engineered with replaceable membranes, the Aquasystem series allows for in-situ servicing, which prevents water from coming into contact with the internal steel shell. This feature significantly reduces the risk of internal corrosion and extends the overall lifespan of the vessel.
Features and Benefits:
- Durable stainless steel bolted flange to prevent corrosion.
- Generously wide membrane opening to minimise noise caused by restricted flow.
- Internal membrane design that prevents water contact with the steel shell, inhibiting internal corrosion.
- Comprehensive capacity range from 2 to 5000 litres, suitable for all heating applications.
- All models come with a replaceable membrane, allowing maintenance without the need to remove the vessel.
- Includes a pre-charge valve for easy air pressure adjustments.
- Specifically designed for heating applications only.
